One way to find the answer to your question might be to browse the abstracts from prior science fairs: These can be found through Google searches. For example, here are a few:http://www.usc.edu/CSSF/History/2001/Projects/
Here is an archive of abstracts for prior year California State Fairs:http://www.usc.edu/CSSF/History/
Here is an archive for a number of past Minesota State Fairshttp://www.fair.mnmas.org/sfAbstracts.asp
This archive for ISEF project abstracts is definite;y worth browsing! https://apps.societyforscience.org/abstracts/
I am afraid you will need to browse thse abstracts manually as I doubt any of them cite the Science Buddies “out of Control” project idea explicitly, even if they are relevant to the idea in the writeup. I suspect relevant projects could be cited under Computer, Psychology, Behavioral and Social Sciences, or other categories depending on the fair and the particular interests of the participants. If I were searching for this on the internet I would think it might be in a Human - Computer Interaction or videogame design context.
If you look hard enough I think you will find relevant projects or get your own original idea that will convince even your teacher, skeptical though she may now be.
